Creative Coding with Codecademy #8: Audio Visualizations with p5.sound.js10,450 ViewsApr 27, 2021
Welcome to Creative Coding with Codecademy!
In our final session, Curriculum Developers Jiwon and Nick show us how to add audio to a p5.js sketch. Check out the full course here: https://j.mp/3gtaxmg
- In this video, we will create audio visualizations using the p5.sound.js library. Our team will learn how to load sound files to our p5.js sketches and talk about analyzing sound with FFT (Fast Fourier Transform). Using amplitude values along the frequency spectrum, they will create an animation that reacts to sound.
